Brown-banded Cockroaches (Nearly Identical to American Cockroaches)
Supella longipalpa (Serville)
Adult male brown banded cockroaches are about 1/2-inch-long and light brown, with fully developed wings. The adult females are shorter and stouter than the males and their wings do not cover the entire abdomen. Both adults and nymphs can be distinguished by the two brownish, broad bands across the body at the base of the abdomen and at mid-abdomen. Both males and females are quite active; adult males fly readily when disturbed.
Brown banded cockroaches prefer warm and dry locations, such as near refrigerator motor housings, on the upper walls of cabinets, and inside pantries, closets, dressers, and furniture in general. They can also be found behind picture frames and beneath tables and chairs, and inside clocks, radios, light switch plates, doorframes, and dressers. It is common to find them hiding nearer the ceiling than the floor and away from water sources.
The brown banded cockroach has three developmental stages: egg, nymph, and adult. Eggs are laid in capsules, which the female carries for about 30 hours before she fastens it on walls, ceilings, and in protected and hidden areas. A female adult has a life span of 13 to 45 weeks; each female produces about 600 descendants per year.
